A while back, in 1.0.4 (I think?), Chazara made a portion of the Super Metroid world, Zebes, as an adventure map, but didn't finish it. He put a ton of time into it from what I remember, and I playtested it pretty thoroughly. It was a fun project at the time, and when he left, a while later, I picked up the remainder of it to finish it.
I'm not exactly proud of it as it's basically a copy of the Super Metroid world, so while it took a lot of effort, it didn't require a ton of creativity. Still, it ports very well. Most of it was done in TEdit while Chazara might have used a little Buildaria for testing, and I might have done the same. Suffice it to say, the items are a little outdated, and it is a pretty typical style of adventure map with tricky jumps and it maintains a fair amount of difficulty (until the last weapon).
The goal is to collect as many gems as possible, and try to die as little as possible of course.
You can try to finish the map, then post your outcome here, points being:
Sapphire - 1 pt
Emerald - 5pts
Ruby - 5pts
Topaz - 10pts
Amethyst - 10pts
Diamond - 30pts
For an optional challenge, each death will subtract 1 point.
